well springs are sold if that helps you. Derek from the board bought them and actually the springs have 7 leafs for the rear and 6 leafs for the front and i dont think they are 4 inches of lift.... i believe they are either 6 inches or 7 inches. with that many inches of lift you gotta get a drop drag link or ifs steering with crossover. then you gotta lengthen your driveshafts... those springs are pretty arched.... well derek from the board will see if he could use em on his truck if not then you could pm him.....he probably will end up selling them again....
